The (Control-M/Server and Control-M/Agent) Installation Guide specifically mentions that a "..non-interactive (silent) installation and upgrade procedure is also available for CONTROL-M/Agent for Microsoft Windows..".
Look for the section titled "Silent installation of CONTROL-M/Agent for
Microsoft Windows". For v6.3.01 this is on page 55 (of 124).
You then want to install the latest-and-greatest cumulative Fix Pack maintenance for the version of the Control-M/Agent, which will also have a Silent installation option.
